This invention relates todouble hung win- (lows and is in the nature of an improvement on the class of windows shown in my United States Patents No. 1,459,668 of June 19,1923 and No. 1,512,741 of Oct. 21, 1924.

- r The present invention and improvements part hereof an scribed hereinafter.

semblage embodying the present invention. 5 Fig. 2 is, a vertical, elevational view par- 1 tiall-y in vertical cross section at line 2-2 of Fig. .1; and

Fig. 8 is a transverse, horizontal view tially in horizontal cross section at line of Fi 1.

In d ig. 2 the illustration is brolren into three parts by waved lines. It is to be noted that the structure of the two opposed sides of the window frame are of identical construction and therefore that only one side as illustrated in Fig. 3 is described.

Similarly the two vertical sides of each sash are of identical construction and only one side is described. g

Fig. 4 is an elevational detail showing the horizontal and vertical, joint-forming ribs of the window frame, back ofthe upper sash.

Referring to the drawings:

Wind frame construction-The metal window sill (Fig. 2) has a dependent, interior flange 1 the upper portion of which extends into a fiat, horizontal ledge 2 at the outward side of which there is a downwardly extending shoulder 3 that merges into a horizontal sill portion 4. Following the structure outwardly in the direction of the outside of a building, sill portion 4 merges in a vertical wail 5 which forms the interior side of a trough 6 the outward wall of which is a joint wall 7. From this joint wall the upper surface of the sill slopes downwardly and outwardly at 8 and terminates in 'a shoulder 9 which overhangs a drift water receiving cove 10 formed by a forwardly projecting bend a of the metal below shoulder 9. From bend a the sill extends outwardly and downwardly at 11 and terminates in an outward or exterior, dependent flange 12. The sill' is 'a one piece metal ,14 being he elevational "view of L ,"a metal window. frame and metal sash asaris '1 ing strip. Outwardly of recess19 the top structure which extends transversely'along the bottom of the window frame.

'Each of the twofront, interior, vertica stop moldings 13 has its under end against an end portion of sill portion 4, and at their upper ends the stop moldings severally meet Y the interior, transverse, horizontal, top stop molding14 which is of the same cross sectional contour as the vertical stop moldings 13. The latter and the top stop molding areheld in place by screws 15, the molding verse, horizontal, top jamb 16 having a front, upwardly extending flange 17 which terminates in a horizontal flange 18 for end to the under side of a'transgagement with structural material. Outwardly of flange 17, top to form on its under s de a three-walled, transverse recess 19 for rece tion of the up or portion of'a transverse, horizontal partjamb has a portion 20 the under surface of which forms an upper stop for the outside, upper sash. Portion 20 merges, in the outward direction, in a downwardly extending wall 21which merges with a flat, horizontal portion 22 that outwardly merges with an upwardly extending portion 23 which terminates in a bent end 24 for engagement with structural material and forming a receptive space for caulking between the metal jamb and the masonry and opposedly to the bent interior end 18.

The open side of the top stop 'molding 14 is next the under side of the top jalnb 16, and has an outward vertical wall 25. The,

jamb 16 is offset recess 19, along the under side of top jamb At each of its vertical sides, one of which is shown in 'Fi 3, the window frame or jamb structure 1S provided with a vertical, three-sided, sheet metal, weight-pocket receiving member 29 having vertical parallel sides 30 one of which terminates in an inward hook 31. The outward or rearward.

side 30 terminates in a hook 32. The hooks serve as anchoragesin structural material.

Hook 31 receives the forwardly turned, flange 33 of a vertical, right angular, side jamb member having a front portion 34 and a thereto right angularly, 'rearwardly extending portion 35.

Hook 32 receives the outwardly turned flange 36 of a vertical side jamb member which has an outside forming portion 37 parallel to portion 34. Portion 37 merges into a forwardly turned, straight portion 38 which merges into a ortion 39 bent in the direction of the welght-receiving pocket. Portion 39 merges into. a forward, turned bent portion 40 which is transversely aline'd- The inward stop molding 13 is clamped to jamb portion 35 by a screw and'ofiset' margin 42'is similarly clamped to portion 40 by a screw 43. Each molding 13 has an inwardly and laterally projecting, vertical wall 44 which forms the front wall .of a vertical, front sash receiving groove. Wall 44 is parallel to and spaced apart-from the vertical wall portion 39 and wall 39 forms the outward vertical wall of an outer sash receiving roove.

Jamb p ate 41, between its vertical'margins, is offset to form a vertical groove 46 for reception of a side of a vertical parting strip 47 which is clamped in the groove by a screw 48. Each vertical parting stri 47 is oppositeliy formed, on its forward an back ward si es, with a lengthwise extending, vertical groove 49 for reception of sash members. The under, forward sash thus vertically movable between the stop molding wall 44 and the bottom of the forward groove 49, the upper and outward sash bei movable between the rearward wall of the ttom of the rear groove 49 and the wall39..

The weight receivin chamber is indicated by 50, the back weig t for the up r sash by 51, the front weight for the un r sash by 52 and a vertical weight separator by 53.

Looking at Fig. 2, it will be seen that the inward surface of vertical jamb plate 41 forms the bottom of the vertical groove in which the edge of. the under, forward-sash slides, while Fig. 3 shows that theinward and flush surfaces 54 of portion 40 and of plate 41 form the bottom of the groove in which an edge of the upper and outer sash slides. 1

The under end of parting strip 47 is beveled outwardl and downwardly at 47'; the under end of of which forms the surface 54, is also slanted portion .40, the inward side 4 y outwardl and downwardly at 54, and the under end of the outeriportion 38 is similarly slanted downwardlyand outwardly at-38, so that these three members severally bottom on and bear against the downwardlyand outwardl slantingsill portion 11'.

Novel eatures of the window frame struc 7 two are the shoulder 3 to prevent water of condensation on theinside of-the undersashstrip 47 with its Y for reception of when jection, forming pockets between the sash projection and theoutwardedgesof the 1 grooves of the upper and of the vertical parting strips.

The vertical grooves 49 at the outer side of the parting strips 47 serve in an important way to receive driving water from storms and to prevent it from leaking inwardly past the lower sash in its closed position, because such water is conducted downwardl and dischar ed on the sill portion 11 by suc rooves. T e grooves 49, both front and bac discharge downwardl and outwardly on the sill portion 11. gill portion 8 is preferably formed with weep holes 8v communicating with drift-water cove 10.

Lower sash c0net1'wotion.-The lower and interior sash for lass comprises a three flanged, .cham ered bottom frame the upper wall 61 of which has a front, vertically dependent, transversely extending flange 62' the. under end of which, as the sash is lowered, contactswith wall 7 of groove 6 and makes a weather tight joint between the cam wall 7 and the sill. Upper wall 61 also has a dependent, vertical, transverse flange 63. which, when the window is closed down, contacts with the shoulder '9 and makes, a weather tight joint by such contact, coming into contact with shoulder 9 before flange 62 contacts with wall 7 and drawing flange 62 into hard cont-act with wall 7. The flanges 62 and 63 are so spaced apart that weather tight joints are formed by the two lines of close contact at shoulder 9 and wall 7. The bottom of chamber 64 is Y I formed by the downwardly and'outwardly inclined, sill portion 8. Wall 61 also has an upwardly extending, vertical transverse flange 65 which serves as an abutment for the outer side of glass 60. The glass holding llfieans are old and need not be described.

'5 under sash comprises at its upper end a top sash member 66 which is formed at its upper, front corner ortion, forwardl of the plane of the rear si e of glass wit a transversely extending, open top trough 67. The bottom wall of the trough is formed by a horizontal, transversely projecting flange 68 that terminates in an upstanding flange 69 which forms the front wall of the trough. The back wall of the trough is formed by the front side of sash member 66 above the bottom trough wall 68,

A three sided channel bar 70 has its under, open side opposed to bottom wall 68 and is located between the front and back walls of the trough and clamped in the trough by a screw 71 through the upper wall of the channel bar and entrant in the bottom trough wall 68. Sash member 66, out war 1y of the trough wall 68, has considerable thickness. Its underside has a lengthwise extending groove 72. The back surface 73 of the sash member 66 is vertical from the under edge 74 of the rear wall of groove 72, the latter being for reception of a transverse fiange 75 which extends upwardly and forwardly from the transverse under member 76 of the upper sash along the bottom of the upper and outward sash holding glass 77. In consequence of the contact be-.

tween the flange 75 and walls of the groove 72, an air pocket is formed between them. Said sash member 76 has a front, fiat wall making a tight joint with surface 73 when the upper and under sashes are closed. Member 76 has a rear, dependent flange 78 which is parallel to its forward, downwardly projecting flange 79 from which the upwardly, forwardly extending flange extends.

The upper and outward sash is provided with a three walled, open sided, rectangular air chamber forming member the bottom wall of which is indicated by 80. It has spaced apart, vertical, upwardly extending sides 81 and 82. Side 82, when the sash is up, contacts with the back wall 27 of the upper transverse parting strip. The rear wall 81 then contacts with the forward, free edge of a transverse horizontal joint and pocket forming rib 92 described below.

Each vertical edge (Fig. 3) of the under sash is provided with a vertical, three sided sash member 85 provided with a vertical, rearwardly projecting rib 86 which moves freely in the front slot 49 of a vertical parting strip 47. Each vertical side of the upper,-outward sash is provided with a vertical, three walled, sash member 87 having a forwardly extending rib 88 that works freely in the rear groove 49 of vertical parting strip 47. Thus the two\ chambers referred to are formed on each side of each of the two parting strips 47.

Important features of the sash structure are: The flange 62 that closes down into the groove 6 to make a. weather tight joint thereat, and the flange 63 which is longer than the therewith parallel, front flange 62; the projecting ribs 86 and 88' that slide in the recesses 49 with their exposed-edges in contact with the bottom walls of the recesses, thereb forming at the front and back sides of eac vertical parting strip, a vertical air pocket and water guldeway. Such water guideways are of special importance because when driving rain strikes against the under closed sash, when the upper sash is closed water cannot pass between thesides of the under sash and opposed frame members but being arrested 1n the inwardly direction by the break joint construction, arising from the rib and groove wall construction, flows downwardly and is discharged from the front and back open sides of the groove 49 on the outwardly and. downwardly sloping sill portion 11,

The sash members (Fi 2) 66 and 76 with the air pocket at 72 and weather-tight joint when the sashes are in closed position The members 85 and 87 form air pocketed, weather-tight means cooperative with vertically opposed portions of the window frame, at both vertical sides of the sash. The lengthwise extending cove l0 insures the outward discharge of rain driving from the outside against the sashes and the downwardly and rearwardly sloping sill portion 11; and the weather and orm a water-tight water tight joints at 7 and 9 prevent the drift of driving rain from passing the closed under sash onto the interior portion of the window sill. Thus the construction insures erfect wind and water-tightness around all our edges of the sashes and also at contact of the members 66 and 76; the transverse, rearwardly facing shoulder 3 also preventing flow into the room of interior, water condensation.

The rib 86 is extruded from the back side of the vertical member 85 or stile of the under sash, rib 88 being similarly extruded from the front side of the vertical member 87 or stile of the upper sash. The free edge of each vertical rib 86 and 88 contacts with the bottom of its receiving groove in the parting strip only when the sashes are drawn together by locking the sash drawing and locking device 89. n Fig. 1, the device 89 is shown in sash drawing and locking position for the upper and lower sash which are which 'it is then drawn into contact. In this position there are clearances at 91; there being a vertical front clearance 91 between the back wall 44 of molding 13 and the front wall 92 of the member or st1le'85; and a rear clearancebetween..the' back wall 93 of the upper-sash member or stile 87. I It is now to be notedthat whenthe sash devices 89 and are freely raisable and lowerable and friction joints, during sash raising and lowering movements, between the parting strips and sash stiles are avoided. This obviates sticking of the sashes in their gu deways and renders it easy to raise and lower these heavy, metal sashes without strain on the 1 person lifting or lowering the sashes.

, and jam The sash drawing and locking device 89 and the sash binders 90 are described in my Patent No. 1,459,668 of June 19, 1923 in which adouble hung window is shown.

This present application relates to an improvement in the construction set forth in my pending application Serial No. 95,251, filed March 17, 1926 for double hung windows. In the present invention, the window casing j amb portion 21, where it merges into the bent portion 22 is formed with an extended joint-forming, forwardly projecting rib 92 the free edge of which is opposedto the back wall 81 of upper sash members 80 forming not only a slight clearance between such free edge and wall, when the upper sash is in fully raised position, but a weather excluding gocket 94 above the rib, between it portion 20-and the there opposed, spaced apartwalls 81 and21.

Referring now to the sash members or rails 66 and 76, the bottom wall of the inverted groove 72 is shaped as an arc of a circle and forms a tight joint-forming wall 94" with and against which the lengthwise ext-ending, cross-sectionally rounded, and extruded free edge 95 int'eriorly contacts with the -arced wall 94 and as such edge and wall are progressively forced together, the contacting surfaces of the edge 95 and wall 94 ride one on the other, until they are in weather excluding contact. Then there is formed at the back side of flange 75, a closed weather excluding air-pocket 96 between the flange and thereto opposed walls of the lower sash member 66 and the downwardly projecting flange 79 sash member, or under rail, 76 of the upper sash.

- In the new form, it will be noted that the rounded, free edge 95 of the flange of the under rail of the upper sash, when it contacts in a closing movement with the arced bottom 94 of the inverted trough of the upperrail of the lower sash, effects a selfadiusting, weather excluding 'oint.

. tvis also to be noted that ,t e upper wall 61,, between the transverse sill flanges 62 and 63 has a length which is substantially less than the'distance between the front wall 7 of the sill groove 6 and the hack, free edge of the shoulder 9, whereby when the back flange 63 partially contacts, on a closing movementof the under sash, with the upper corner portion of shoulder 9, the two flanges thereto adjacent air and water pocket 94 (Fig. 2) are, continued vertically downwards of the rearward, window frame stiles 38 to the sill. At the junction of each vertical member'or stile 38 with its portion 39, there is extruded a forwardly projecting, vertical rib 97, the free edge of which is closely'adjacent the back, vertical side member 93 of the upper sash. Between each member 93 of the upper sash, the vertical wall portion 39 of the window frame stile, a rib 97 and the vertical portion 40 of the stile with which its portion 39 merges, there is formed a vertical air and Water pocket 98. The horizontal, joint-forming ribs 92 and the pockets 94 are severally in alignment with a vertical'rib 97 and air pocket 98. Thus the horizontal, joint forming rib 92 and adjacent air pocket 94 at each end are extended downwardly, to the s ll.

The vertical stile portion 39 (Fig. 3) of the Window frame is a bent portion at right angles to the flat frame portion 38 and flat frame portion 40 is at right angles to the bent portion 39. The vertical plate 41 has its inner surface in alignment with the inner surfaces of the rearward portion 40 and the inner surfaces of portions 40 and 41 are continuous and form elongated walls of a guideway. for the under and upper sashes which are spaced apart by a vertical parting strip that is detachably secured to the inner side of the vertical frame portion 41, the rearward, widegroove of the parting strip being opposed to and spaced apart from the bent portion 39; a free edge of a Wall of the trough in the parting strip being opposed to the free, forwardly extending edge of the joint-forming rib 97. So also in Fig. 2, the top horizontal amb portion 21 of the window frame is bent at right angles to the flat jamb portion 22 and the elongated v the bent portion 21. The free, forwardly projecting edge of the top, joint-forming rib 92 is opposed to the under, rear corner portion of the top, horizontal parting strip. I

As shown in Fig. 2, there is only one air chamber and water way 94 and it is horizontal, but it communicates at each end with a vertical air chamber and water way 98 shown in Fig. 3; and each of these verticalchambers 98 is opposed to and spaced apart:

from the two water-ways 49 formed on the rear side of the parting strip by the projectionof the narrow sash rib 88 into the much wider, rear groove of the'parting strip between the side walls thereof, so as to form at each side of each rib 88 a vertical air and water chamber or way 49.

The cross sectional, arcuate, ,fre edge or rib 95 overhan s the rear side of the subjacent wall of auge 75. The front wall of the inverted groove 72 slopes curvingly downwards and rearwardly from itsarcuate bottom or under wall 94. that when the sashes are closed and. drawn together, a weather excluding joint is formed along the up er and thereto rearward, peripheral POItlOllS' of the free edge or rib 95 and the arcuate wall. The joint thus formed is peculiarly efiicient as a weather excluding joint and is a substantial and important feature of the present invention. The horizontal, diametric dimension of the-arced, free edge of rib 95, above the subjacent portion of the flange, is greater than the thicknex of the flange so that the rear, peripheral portion of the free edge makes an initial sliding contact with said downwardly and back-2' wardly curving wall of the groove. Said structure and mode of operation are believed to'be novel in the art. The front edge of the extruded ribs 92 and 97 are smooth and flat for conta'ct with the rear surfaces of the top and side members of the rear sash.

The upwardly and forwardly projecting portion of flange 75 is springable laterally. When the back, upper sash is slid up the arced upper wall of the flange 75 initially strikes against the rear downwardly curving wall of the groove or trough 72, and as the back upper sashis forced upwardly into its final closing position, the arced wall of the flange lodges finally and firmly against the arced bottom or joint forming wall 94; and when the sash drawing and locking device 89 is closed the contacting, arced, transversely extending surfaces of the trough and The result is are drawn tightly into weather exclu g position. Y
